Method Details

initialize

public IRubyObject initialize(ThreadContext context,
 IRubyObject[] args)

offset

public final int offset()

ffiType

public final Type ffiType()

equals

public boolean equals(Object obj)

Description copied from class: RubyObject

This override does not do a "checked" dispatch.

Overrides:

equals in class RubyObject

Parameters:

obj - object to compare

Returns:

true if equals

See Also:

• RubyBasicObject.equals(Object)

hashCode

public int hashCode()

Description copied from class: RubyObject

This override does not do "checked" dispatch since Object usually has #hash defined.

Overrides:

hashCode in class RubyObject

Returns:

the hash code

See Also:
