AbstractLocalVariableTable
public AbstractLocalVariableTable(AbstractLocalVariableTable c)
- Initialize from another object. Note that both objects use the same
references (shallow copy). Use copy() for a physical copy.
AbstractLocalVariableTable
public AbstractLocalVariableTable(int name_index,
int length,
LocalVariable[] local_variable_table,
ConstantPool constant_pool)
- Parameters:
name_index
- Index in constant pool to `LocalVariableTable'length
- Content length in byteslocal_variable_table
- Table of local variablesconstant_pool
- Array of constants
dump
public final void dump(java.io.DataOutputStream file)
throws java.io.IOException
- Dump local variable table attribute to file stream in binary format.
- Overrides:
dump
in class Attribute
- Parameters:
file
- Output file stream
- Throws:
java.io.IOException
getLocalVariableTable
public final LocalVariable[] getLocalVariableTable()
- Returns:
- Array of local variables of method.
getLocalVariable
public final LocalVariable getLocalVariable(int index)
- Deprecated. since 5.2 because multiple variables can share the
same slot, use getLocalVariable(int index, int pc) instead.
- Parameters:
index
- the variable slot
- Returns:
- first matching variable using index
getLocalVariable
public final LocalVariable getLocalVariable(int index,
int pc)
- Parameters:
index
- the variable slotpc
- the current pc that this variable is alive
- Returns:
- matching variable using index when variable is used at supplied pc
setLocalVariableTable
public final void setLocalVariableTable(LocalVariable[] local_variable_table)
toString
public final java.lang.String toString()
- Overrides:
toString
in class Attribute
- Returns:
- String representation.
copy
public Attribute copy(ConstantPool _constant_pool)
- Specified by:
copy
in class Attribute
- Returns:
- deep copy of this attribute
getTableLength
public final int getTableLength()
