Method Detail

initialize

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

offset

public final int offset()

ffiType

public final Type ffiType()

equals

public boolean equals(java.lang.Object obj)
Description copied from class: RubyObject
This method is just a wrapper around the Ruby "==" method, provided so that RubyObjects can be used as keys in the Java HashMap object underlying RubyHash.

Overrides:
equals in class RubyObject

hashCode

public int hashCode()
Description copied from class: RubyObject
Override the Object#hashCode method to make sure that the Ruby hash is actually used as the hashcode for Ruby objects. If the Ruby "hash" method doesn't return a number, the Object#hashCode implementation will be used instead.

Overrides:
hashCode in class RubyObject

isCacheable

public final boolean isCacheable()
Gets the cacheable status of this Struct member

Returns:
true if this member type is cacheable

isValueReferenceNeeded

public final boolean isValueReferenceNeeded()
Checks if a reference to the ruby object assigned to this field needs to be stored

Returns:
true if this member type requires the ruby value to be stored.

size

public final IRubyObject size(ThreadContext context)

alignment

public final IRubyObject alignment(ThreadContext context)

offset

public final IRubyObject offset(ThreadContext context)

type

public final IRubyObject type(ThreadContext context)

name

public final IRubyObject name(ThreadContext context)
