public void addEntry(int startPc, int length, int nameIndex, int descriptorIndex, int index)
local_variable_table
.
startPc
- start_pc
length
- length
nameIndex
- name_index
descriptorIndex
- descriptor_index
index
- index
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 AttributeInfo
newCp
- the constant pool table used by the new copy.classnames
- should be null.
