Class FixedField10

java.lang.Object
db.Field
db.BinaryField
db.FixedField10
All Implemented Interfaces:
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 Details

    • 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

    • INSTANCE

      public static final FixedField10 INSTANCE
      Instance intended for defining a Table Schema

  • Constructor Details

    • 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:
      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:
      IllegalArgumentException - thrown if data is not 10-bytes in length

  • Method Details

    • 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 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

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class BinaryField

    • equals

      public boolean equals(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 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
