Constructor Detail

LocalVariable

public LocalVariable(int index)

Constructor.

Parameters:

LocalVariable

public LocalVariable(java.lang.String name,
                     Type type,
                     int index)

Constructor.

Parameters:

name - The name of the local variable.

type - The descriptor (or index into the constant pool) representing the variable type.

index - The index of the local variable in the method's local variable array.

Method Detail

hashCode

public int hashCode()

Hash the local variable. A stricter hashing than using the index will break Hashtable lookups since a variable could have a name assigned to it after its first use.

Overrides:

hashCode in class java.lang.Object

Returns:

The hash code.

equals

public boolean equals(java.lang.Object obj)

Check if an object is equal to this variable. A stricter comparison than comparing indices will break Hashtable lookups since a variable could have a name assigned to it after its first use.

Overrides:

equals in class java.lang.Object

Parameters:

obj - The object to compare against.

Returns:

true if equal, false if not.

name

public java.lang.String name()

Get the name of the local variable.

Returns:

The name of the local variable.

type

public Type type()

Get the type of the local variable.

Returns:

The type of the local variable.

index

public int index()

Get the index into the local variable array.

Returns:

The index into the local variable array.

toString

public java.lang.String toString()

Convert the variable to a string.

Overrides:

toString in class java.lang.Object

Returns:

A string representation of the variable.
