Method Details
-
addEntry
public void addEntry(int startPc, int length, int nameIndex, int descriptorIndex, int index) Appends a new entry tolocal_variable_table.- Parameters:
startPc-start_pclength-lengthnameIndex-name_indexdescriptorIndex-descriptor_indexindex-index
-
shiftIndex
public void shiftIndex(int lessThan, int delta) For eachlocal_variable_table[i].index, this method increasesindexbydelta.- Parameters:
lessThan- the index does not change if it is less than this value.
-
tableLength
public int tableLength()Returnslocal_variable_table_length. This represents the number of entries in the table. -
startPc
public int startPc(int i) Returnslocal_variable_table[i].start_pc. This represents the index into the code array from which the local variable is effective.- Parameters:
i- the i-th entry.
-
codeLength
public int codeLength(int i) Returnslocal_variable_table[i].length. This represents the length of the code region in which the local variable is effective.- Parameters:
i- the i-th entry.
-
nameIndex
public int nameIndex(int i) Returns the value oflocal_variable_table[i].name_index. This represents the name of the local variable.- Parameters:
i- the i-th entry.
-
variableName
Returns the name of the local variable specified bylocal_variable_table[i].name_index.- Parameters:
i- the i-th entry.
-
variableNameByIndex
Returns the name of the local variable with given index. If you want to get the parameter name of method with correct order, you should using this method.- Parameters:
index- the index of the local variable.
-
descriptorIndex
public int descriptorIndex(int i) Returns the value oflocal_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.- Parameters:
i- the i-th entry.
-
signatureIndex
public int signatureIndex(int i) This method is equivalent todescriptorIndex(). If this attribute represents a LocalVariableTypeTable attribute, this method should be used instead ofdescriptorIndex()since the method name is more appropriate.- Parameters:
i- the i-th entry.- See Also:
-
descriptor
Returns the type descriptor of the local variable specified bylocal_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.- Parameters:
i- the i-th entry.
-
signature
This method is equivalent todescriptor(). If this attribute represents a LocalVariableTypeTable attribute, this method should be used instead ofdescriptor()since the method name is more appropriate.To parse the string, call
toFieldSignature(String)inSignatureAttribute.- Parameters:
i- the i-th entry.- See Also:
-
index
public int index(int i) Returnslocal_variable_table[i].index. This represents the index of the local variable.- Parameters:
i- the i-th entry.
-
copy
Makes a copy.- Overrides:
copyin classAttributeInfo- Parameters:
newCp- the constant pool table used by the new copy.classnames- should be null.
