Class AliasDefSeg

    • Constructor Detail

      • AliasDefSeg

        public AliasDefSeg()

      • AliasDefSeg

        public AliasDefSeg​(java.util.List<PathSegment> selectors)

    • Method Detail

      • getAliasOf

        public java.util.List<PathSegment> getAliasOf()

      • setAliasOf

        public void setAliasOf​(java.util.List<PathSegment> aliasOf)

      • getSizeImpl

        public int getSizeImpl​(DataContext ctx)
        Description copied from class: DataDefinitionSeg
        Return the number of bytes occupied by a single instance of the given data type. When the data is indirect, size is zero. When the data is variable length, size is -1;
        Specified by:
        getSizeImpl in class DataDefinitionSeg
        Returns:
        Number of bytes.

      • minSize

        public int minSize​(DataContext ctx)
        Description copied from class: DataDefinitionSeg
        Some data types need to offer a range of sizes for the encoded form of their data. The common case is fixed.
        Overrides:
        minSize in class DataDefinitionSeg
        Returns:

      • maxSize

        public int maxSize​(DataContext ctx)
        Description copied from class: DataDefinitionSeg
        Some data types need to offer a range of sizes for the encoded form of their data. The common case is fixed.
        Overrides:
        maxSize in class DataDefinitionSeg
        Returns:

      • alignment

        public int alignment​(DataContext ctx)
        Description copied from class: DataDefinitionSeg
        Alignment is normally the natural size of a primitive element. Structured types and variable length types must override this method.
        Overrides:
        alignment in class DataDefinitionSeg
        Returns:

      • construct

        protected BaseDataType<?> construct​(int[] dimensions,
                                    DataContext ctx)
        Aliases are only constructed when accessed individually, when they behave as a solo target.
        Specified by:
        construct in class DataDefinitionSeg
        Parameters:
        dimensions -
        ctx -
        Returns:

      • simpleString

        public java.lang.String simpleString()
        Description copied from class: PathSegment
        Supply s simple descriptive name usable when browsing a hierarchy. A simple type name for elementary types, a non-detailed description for complex types.
        Specified by:
        simpleString in class PathSegment
        Returns:

      • set

        public PathSegment set​(java.nio.ByteBuffer source,
                       boolean padded)
        Description copied from class: PathSegment
        Replace the current instance content with the decoded source bytes.

        The caller must ensure that the instance is appropriate for the bytes supplied. This permits instance re-use in optimized applications.

        Specified by:
        set in class PathSegment
        Parameters:
        source - The bytes to be decoded. The position will be left after the last byte of the decoded segment.
        padded - Alternate format selection. Packed format when false.
        Returns:
        The same instance.

      • put

        public void put​(java.nio.ByteBuffer dest,
                boolean padded)
        Description copied from class: PathSegment
        Encode the current instance to the given destination.
        Specified by:
        put in class PathSegment
        Parameters:
        dest - The buffer receiving the complete encoded instance.
        padded - Alternate format selection. Packed format when false.

      • getBytes

        public int getBytes()
        Description copied from class: PathSegment
        Obtain the number of bytes needed to encode this segment instance in packed format.
        Specified by:
        getBytes in class PathSegment
        Returns:
        Number of bytes, assuming put() will be called with padded false.

      • getTokens

        public java.util.List<java.lang.String> getTokens()
        Specified by:
        getTokens in class PathSegment

      • equals

        public boolean equals​(java.lang.Object o)
        Overrides:
        equals in class PathSegment

      • hashCode

        public int hashCode()
        Overrides:
