public void shiftIndex(int lessThan,
int delta)
local_variable_table[i].index,
this method increases index by delta.
lessThan - the index does not change if it
is less than this value.public int tableLength()
local_variable_table_length.
This represents the number of entries in the table.
public int startPc(int i)
local_variable_table[i].start_pc.
This represents the index into the code array from which the local
variable is effective.
i - the i-th entry.public int codeLength(int i)
local_variable_table[i].length.
This represents the length of the code region in which the local
variable is effective.
i - the i-th entry.public int nameIndex(int i)
local_variable_table[i].name_index.
This represents the name of the local variable.
i - the i-th entry.public java.lang.String variableName(int i)
local_variable_table[i].name_index.
i - the i-th entry.public int descriptorIndex(int i)
local_variable_table[i].descriptor_index.
This represents the type descriptor of the local variable.
If this attribute represents a LocalVariableTypeTable attribute,
this method returns the value of
local_variable_type_table[i].signature_index.
It represents the type of the local variable.
i - the i-th entry.public int signatureIndex(int i)
descriptorIndex().
If this attribute represents a LocalVariableTypeTable attribute,
this method should be used instead of descriptorIndex()
since the method name is more appropriate.
i - the i-th entry.descriptorIndex(int),
SignatureAttribute.toFieldSignature(String)public java.lang.String descriptor(int i)
local_variable_table[i].descriptor_index.
If this attribute represents a LocalVariableTypeTable attribute,
this method returns the type signature of the local variable
specified by local_variable_type_table[i].signature_index.
i - the i-th entry.public java.lang.String signature(int i)
descriptor().
If this attribute represents a LocalVariableTypeTable attribute,
this method should be used instead of descriptor()
since the method name is more appropriate.
To parse the string, call toFieldSignature(String)
in SignatureAttribute.
i - the i-th entry.descriptor(int),
SignatureAttribute.toFieldSignature(String)public int index(int i)
local_variable_table[i].index.
This represents the index of the local variable.
i - the i-th entry.
public AttributeInfo copy(ConstPool newCp,
java.util.Map classnames)
copy in class AttributeInfonewCp - the constant pool table used by the new copy.classnames - should be null.
