public IRubyObject call(ThreadContext context, IRubyObject self, RubyModule klazz, String name, IRubyObject[] args, Block block)

Implements abstract org.jruby.internal.runtime.methods.DynamicMethod.call.

Doc from org.jruby.internal.runtime.methods.DynamicMethod.call.

The minimum 'call' method required for a dynamic method handle. Subclasses must implement this method, but may implement the other signatures to provide faster, non-boxing call paths. Typically subclasses will implement this method to check variable arity calls, then performing a specific-arity invocation to the appropriate method or performing variable-arity logic in-line.

Parameters
context:ThreadContext

The thread context for the currently executing thread

self:IRubyObject

The 'self' or 'receiver' object to use for this call

klazz:RubyModule

The Ruby class against which this method is binding

name:String

The incoming name used to invoke this method

args:IRubyObject[]

The argument list to this invocation

block:Block

The block passed to this invocation

Returns:IRubyObject

The result of the call

dupback to summary
public abstract DynamicMethod dup()

Implements abstract org.jruby.internal.runtime.methods.DynamicMethod.dup.

Doc from org.jruby.internal.runtime.methods.DynamicMethod.dup.

Duplicate this method, returning DynamicMethod referencing the same code and with the same attributes. It is not required that this method produce a new object if the semantics of the DynamicMethod subtype do not require such.

Returns:DynamicMethod

An identical DynamicMethod object to the target.

Annotations
@Override
equalsback to summary
public boolean equals(Object other)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
other:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

Annotations
@Override
hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object
