Method Details

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 Object

Returns:

The hash code.

equals

public boolean equals(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 Object

Parameters:

obj - The object to compare against.

Returns:

true if equal, false if not.

name

public 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 String toString()

Convert the variable to a string.

Overrides:

toString in class Object

Returns:

A string representation of the variable.
