Class ValueMap<T2,​T>

  • All Implemented Interfaces:
    Value<T2>, io.aether.utils.ToString
    public class ValueMap<T2,​T>
extends java.lang.Object
implements Value<T2>

    • Constructor Detail

      • ValueMap

        public ValueMap​(Value<T> self,
                io.aether.utils.interfaces.AFunction<T,​T2> mapper)

    • Method Detail

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object

      • toString

        public void toString​(io.aether.utils.AString sb)
        Specified by:
        toString in interface io.aether.utils.ToString

      • enter

        public void enter​(java.lang.Object owner)
        Description copied from interface: Value
        Marks the beginning of value processing by a handler. Called when a processor starts working with this value.
        Specified by:
        enter in interface Value<T2>
        Parameters:
        owner - The object that begins processing this value

      • isData

        public boolean isData()
        Description copied from interface: Value
        Checks if this value contains processable data. Returns false for control values (force, request, close).
        Specified by:
        isData in interface Value<T2>
        Returns:
        true if this value contains data, false otherwise

      • isRequestData

        public boolean isRequestData()
        Description copied from interface: Value
        Determines if this value represents a data request. Request values typically ask for data to be generated/sent rather than containing data themselves.
        Specified by:
        isRequestData in interface Value<T2>
        Returns:
        true if this is a request value, false otherwise

      • data

        public T2 data()
        Description copied from interface: Value
        Retrieves the data payload contained in this value. The actual data type is determined by the generic parameter T.
        Specified by:
        data in interface Value<T2>
        Returns:
        The contained data object, which may be null for special values

      • reject

        public void reject​(java.lang.Object owner,
                   long blockId)
        Description copied from interface: Value
        Rejects the value sending process due to a stream being blocked.
        Specified by:
        reject in interface Value<T2>
        Parameters:
        owner - An object that provides information about the current state of the block.

        When the creator of the Value object receives an reject call, it understands that the stream is currently blocked and data cannot be sent at this moment.

        If, at the same time, a Value object with the isRequestData flag arrives from the stream, a race condition can occur. To resolve this issue, the checkWritable method should be called to determine the actual state of the remote node.

      • priority

        public int priority()
        Description copied from interface: Value
        Returns the processing priority of this value. Higher priority values should be processed before lower priority ones. Default implementation returns 0 (normal priority).
        Specified by:
        priority in interface Value<T2>
        Returns:
        Priority level as an integer (higher = more important)

      • isClose

        public boolean isClose()
        Description copied from interface: Value
        Checks if this value signals stream/processing closure. Close values typically indicate the end of a data stream or processing sequence.
        Specified by:
        isClose in interface Value<T2>
        Returns:
        true if this is a close signal, false otherwise

      • isForce

        public boolean isForce()
        Description copied from interface: Value
        Checks if this value is marked as "force". Force values typically bypass normal processing constraints and must be handled immediately regardless of system state.
        Specified by:
        isForce in interface Value<T2>
        Returns:
        true if this is a force value, false otherwise

      • success

        public void success​(java.lang.Object owner)
        Description copied from interface: Value
        Releases resources associated with this value when it's no longer needed. This is the normal end-of-life operation for a value.
        Specified by:
        success in interface Value<T2>
        Parameters:
        owner - The object initiating the success operation (for tracking/logging)
