int the element for the key or -1 if the key is not defined in the hash table.

hashCode

public int hashCode(Object key)

Return the hashcode for the key parameter

Parameters:

key - org.eclipse.jdt.internal.compiler.lookup.MethodBinding

Returns:

int

put

public int put(Object key,
 int value)
