Class FixedField10

  • All Implemented Interfaces:
    java.lang.Comparable<Field>
    public class FixedField10
extends BinaryField
    FixedField10 provide an unsigned 10-byte fixed-length field value. The most-significant byte corresponds to index-0 (i.e., data[0]).

    • Field Detail

      • ZERO_VALUE

        public static final FixedField10 ZERO_VALUE
        Zero fixed10 field value

      • MIN_VALUE

        public static FixedField10 MIN_VALUE
        Minimum long field value

      • MAX_VALUE

        public static FixedField10 MAX_VALUE
        Maximum long field value

    • Constructor Detail

      • FixedField10

        public FixedField10()
        Construct a 10-byte fixed-length field with an initial value of 0.

      • FixedField10

        public FixedField10​(byte[] data)
        Construct a 10-byte fixed-length field with an initial value of data.
        Parameters:
        data - initial 10-byte binary value. A null corresponds to zero value and does not affect the null-state (see setNull() and BinaryField.isNull()).
        Throws:
        java.lang.IllegalArgumentException - thrown if data is not 10-bytes in length

      • FixedField10

        public FixedField10​(byte[] data,
                    boolean immutable)
        Construct a 10-byte fixed-length binary field with an initial value of data.
        Parameters:
        data - initial 10-byte binary value. A null corresponds to zero value and does not affect the null-state (see setNull() and BinaryField.isNull()).
        immutable - true if field value is immutable
        Throws:
        java.lang.IllegalArgumentException - thrown if data is not 10-bytes in length

    • Method Detail

      • compareTo

        public int compareTo​(Field o)
        Description copied from class: Field
        Compares this Field with another Field for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified Field.
        NOTE: Field objects do not fully comply with the Comparable interface. Only the same Field implementations may be compared. In addition, the null state is not considered when comparing PrimitiveFields which have a zero (0) value.
        Specified by:
        compareTo in interface java.lang.Comparable<Field>
        Overrides:
        compareTo in class BinaryField
        Parameters:
        o - another Field which is the same type as this Field
        Returns:
        field comparison result (see Comparable.compareTo(Object)).

      • copyField

        public db.FixedField copyField()
        Description copied from class: Field
        Create new instance of this field with the same value.
        Returns:
        new field instance with same value

      • newField

        public db.FixedField newField()
        Description copied from class: Field
        Create new instance of this field type.
        Returns:
        new field instance with undefined initial value

      • getBinaryData

        public byte[] getBinaryData()
        Description copied from class: Field
        Get data as a byte array.
        Overrides:
        getBinaryData in class BinaryField
        Returns:
        byte[]

      • setBinaryData

        public void setBinaryData​(byte[] d)
        Description copied from class: Field
        Set data from binary byte array. All variable-length fields must implement this method.
        Overrides:
        setBinaryData in class BinaryField
        Parameters:
        d - field data

      • equals

        public boolean equals​(java.lang.Object obj)
        Description copied from class: Field
        Determine if the specified Object is another Field which has the same type and value as this Field. When comparing a PrimitiveField, with a null state, a value of zero (0) is used.
        Overrides:
        equals in class BinaryField
        Parameters:
        obj - another object
        Returns:
        true if this field equals obj

      • getValueAsString

        public java.lang.String getValueAsString()
        Description copied from class: Field
        Get field value as a formatted string
        Overrides:
        getValueAsString in class BinaryField
        Returns:
        field value string

      • isVariableLength

        public final boolean isVariableLength()
        Overrides:
        isVariableLength in class BinaryField
        Returns:
        true if a Field instance is variable length, else false.

      • isNull

        public final boolean isNull()
        Description copied from class: Field
        Determine if the field has been set to a null-state or value.
        Overrides:
        isNull in class BinaryField
        Returns:
        true if field has been set to a null state or value, else false
