In visitMaxs, a fix point algorithm is -- * used to compute the "input frame" of each basic ast, i.e. the stack map -- * frame at the begining of the basic ast, starting from the input frame -- * of the first basic ast (which is computed from the method descriptor), -- * and by using the previously computed output frames to compute the input -- * state of the other blocks. -- * -- * All output and input frames are stored as arrays of integers. Reference -- * and array types are represented by an index into a type table (which is -- * not the same as the constant pool of the class, in order to avoid adding -- * unnecessary constants in the pool - not all computed frames will end up -- * being stored in the stack map table). This allows very fast type -- * comparisons. -- * -- * OutputAppender stack map frames are computed relatively to the input frame of the -- * basic ast, which is not yet known when output frames are computed. It -- * is therefore necessary to be able to represent abstract types such as -- * "the type at position x in the input frame locals" or "the type at -- * position x from the top of the input frame stack" or even "the type at -- * position x in the input frame, with y more (or less) array dimensions". -- * This explains the rather complicated type format used in output frames. -- * -- * This format is the following: DIM KIND VALUE (4, 4 and 24 bits). DIM is a -- * signed number of array dimensions (from -8 to 7). KIND is either BASE, -- * LOCAL or STACK. BASE is used for types that are not relative to the input -- * frame. LOCAL is used for types that are relative to the input local -- * variable types. STACK is used for types that are relative to the input -- * stack types. VALUE depends on KIND. For LOCAL types, it is an index in -- * the input local variable types. For STACK types, it is a position -- * relatively to the top of input frame stack. For BASE types, it is either -- * one of the constants defined in FrameVisitor, or for OBJECT and -- * UNINITIALIZED types, a tag and an index in the type table. -- * -- * OutputAppender frames can contain types of any kind and with a positive or -- * negative dimension (and even unassigned types, represented by 0 - which -- * does not correspond to any valid type value). Input frames can only -- * contain BASE types of positive or null dimension. In all cases the type -- * table contains only internal type names (array type descriptors are -- * forbidden - dimensions must be represented through the DIM field). -- * -- * The LONG and DOUBLE types are always represented by using two slots (LONG + -- * TOP or DOUBLE + TOP), for local variable types as well as in the operand -- * stack. This is necessary to be able to simulate DUPx_y instructions, -- * whose effect would be dependent on the actual type values if types were -- * always represented by a single slot in the stack (and this is not -- * possible, since actual type values are not always known - cf LOCAL and -- * STACK type kinds). -- */ -- -- /** -- * Mask to get the dimension of a frame type.

-- The ASM framework is organized -- around the {@link org.mvel.asm.ClassVisitor ClassVisitor}, -- {@link org.mvel.asm.FieldVisitor FieldVisitor} and -- {@link org.mvel.asm.MethodVisitor MethodVisitor} interfaces, which allow -- one to visit the fields and methods of a class, including the bytecode -- instructions of each method. -- --

-- In addition to these main interfaces, ASM provides a {@link -- org.mvel.asm.ClassReader ClassReader} class, that can parse an -- existing class and make a given visitor visit it. ASM also provides -- a {@link org.mvel.asm.ClassWriter ClassWriter} class, which is -- a visitor that generates Java class files. -- --

-- In order to generate a class from scratch, only the {@link -- org.mvel.asm.ClassWriter ClassWriter} class is necessary. Indeed, -- in order to generate a class, one must just call its visitXXX -- methods with the appropriate arguments to generate the desired fields -- and methods. See the "helloworld" example in the ASM distribution for -- more details about class generation. -- --

-- In order to modify existing classes, one must use a {@link -- org.mvel.asm.ClassReader ClassReader} class to analyze -- the original class, a class modifier, and a {@link org.mvel.asm.ClassWriter -- ClassWriter} to construct the modified class. The class modifier -- is just a {@link org.mvel.asm.ClassVisitor ClassVisitor} -- that delegates most of the work to another {@link org.mvel.asm.ClassVisitor -- ClassVisitor}, but that sometimes changes some parameter values, -- or call additional methods, in order to implement the desired -- modification process. In order to make it easier to implement such -- class modifiers, ASM provides the {@link org.mvel.asm.ClassAdapter -- ClassAdapter} and {@link org.mvel.asm.MethodAdapter MethodAdapter} -- classes, which implement the {@link org.mvel.asm.ClassVisitor ClassVisitor} -- and {@link org.mvel.asm.MethodVisitor MethodVisitor} interfaces by -- delegating all work to other visitors. See the "adapt" example in the ASM -- distribution for more details about class modification. -- --

In visitMaxs, a fix point algorithm is +- * used to compute the "input frame" of each basic block, i.e. the stack map +- * frame at the beginning of the basic block, starting from the input frame +- * of the first basic block (which is computed from the method descriptor), +- * and by using the previously computed output frames to compute the input +- * state of the other blocks. +- * +- * All output and input frames are stored as arrays of integers. Reference +- * and array types are represented by an index into a type table (which is +- * not the same as the constant pool of the class, in order to avoid adding +- * unnecessary constants in the pool - not all computed frames will end up +- * being stored in the stack map table). This allows very fast type +- * comparisons. +- * +- * Output stack map frames are computed relatively to the input frame of the +- * basic block, which is not yet known when output frames are computed. It +- * is therefore necessary to be able to represent abstract types such as +- * "the type at position x in the input frame locals" or "the type at +- * position x from the top of the input frame stack" or even "the type at +- * position x in the input frame, with y more (or less) array dimensions". +- * This explains the rather complicated type format used in output frames. +- * +- * This format is the following: DIM KIND VALUE (4, 4 and 24 bits). DIM is a +- * signed number of array dimensions (from -8 to 7). KIND is either BASE, +- * LOCAL or STACK. BASE is used for types that are not relative to the input +- * frame. LOCAL is used for types that are relative to the input local +- * variable types. STACK is used for types that are relative to the input +- * stack types. VALUE depends on KIND. For LOCAL types, it is an index in +- * the input local variable types. For STACK types, it is a position +- * relatively to the top of input frame stack. For BASE types, it is either +- * one of the constants defined in FrameVisitor, or for OBJECT and +- * UNINITIALIZED types, a tag and an index in the type table. +- * +- * Output frames can contain types of any kind and with a positive or +- * negative dimension (and even unassigned types, represented by 0 - which +- * does not correspond to any valid type value). Input frames can only +- * contain BASE types of positive or null dimension. In all cases the type +- * table contains only internal type names (array type descriptors are +- * forbidden - dimensions must be represented through the DIM field). +- * +- * The LONG and DOUBLE types are always represented by using two slots (LONG + +- * TOP or DOUBLE + TOP), for local variable types as well as in the operand +- * stack. This is necessary to be able to simulate DUPx_y instructions, +- * whose effect would be dependent on the actual type values if types were +- * always represented by a single slot in the stack (and this is not +- * possible, since actual type values are not always known - cf LOCAL and +- * STACK type kinds). +- */ +- +- /** +- * Mask to get the dimension of a frame type.

+-The ASM framework is organized +-around the {@link org.objectweb.asm.ClassVisitor ClassVisitor}, +-{@link org.objectweb.asm.FieldVisitor FieldVisitor} and +-{@link org.objectweb.asm.MethodVisitor MethodVisitor} interfaces, which allow +-one to visit the fields and methods of a class, including the bytecode +-instructions of each method. +- +-

+-In addition to these main interfaces, ASM provides a {@link +-org.objectweb.asm.ClassReader ClassReader} class, that can parse an +-existing class and make a given visitor visit it. ASM also provides +-a {@link org.objectweb.asm.ClassWriter ClassWriter} class, which is +-a visitor that generates Java class files. +- +-

+-In order to generate a class from scratch, only the {@link +-org.objectweb.asm.ClassWriter ClassWriter} class is necessary. Indeed, +-in order to generate a class, one must just call its visitXXX +-methods with the appropriate arguments to generate the desired fields +-and methods. See the "helloworld" example in the ASM distribution for +-more details about class generation. +- +-

+-In order to modify existing classes, one must use a {@link +-org.objectweb.asm.ClassReader ClassReader} class to analyze +-the original class, a class modifier, and a {@link org.objectweb.asm.ClassWriter +-ClassWriter} to construct the modified class. The class modifier +-is just a {@link org.objectweb.asm.ClassVisitor ClassVisitor} +-that delegates most of the work to another {@link org.objectweb.asm.ClassVisitor +-ClassVisitor}, but that sometimes changes some parameter values, +-or call additional methods, in order to implement the desired +-modification process. In order to make it easier to implement such +-class modifiers, ASM provides the {@link org.objectweb.asm.ClassAdapter +-ClassAdapter} and {@link org.objectweb.asm.MethodAdapter MethodAdapter} +-classes, which implement the {@link org.objectweb.asm.ClassVisitor ClassVisitor} +-and {@link org.objectweb.asm.MethodVisitor MethodVisitor} interfaces by +-delegating all work to other visitors. See the "adapt" example in the ASM +-distribution for more details about class modification. +- +-

+-The size of the core ASM library, asm.jar, is only 42KB, which is much +-smaller than the size of the +-BCEL library (504KB), and than the +-size of the +-SERP library (150KB). ASM is also +-much faster than these tools.
