Class OraCollationKey

java.lang.Object
oracle.i18n.text.OraCollationKey

All Implemented Interfaces:

Comparable

public class OraCollationKey

extends Object

implements Comparable

The OraCollationKey class represents a String object under control of a specific OraCollator object. This construct is used to store a sorting order under a certain sorting rule and to be compared when needed.

Since:

Oracle 10.1.0.2

Method Detail

compareTo

public int compareTo(OraCollationKey target)

Compare this OraCollationKey object to the target OraCollationKey object. The collation rules of the OraCollator object that created these keys are applied. OraCollationKey objects created by different OraCollator objects cannot be compared.

Parameters:

target - the target OraCollationKey

Returns:

OraCollator.GREATER, OraCollator.LESS, or OraCollator.EQUAL

OraCollator.compare(java.lang.Object, java.lang.Object)

compareTo

public int compareTo(Object o)

Compares this OraCollationKey object with the specified Object object.

Specified by:

compareTo in interface Comparable

Parameters:

o - the Object object to which the OraCollationKey object is compared

Returns:

OraCollator.GREATER, OraCollator.LESS, or OraCollator.EQUAL

equals

public boolean equals(Object target)

Determines if this OraCollationKey object and the target OraCollationKey object are equal.

Overrides:

equals in class Object

Parameters:

target - the OraCollationKey object to which this OraCollationKey object is compared

Returns:

ture if the two are equal; false otherwise

hashCode

public int hashCode()

Creates a hash code for this OraCollationKey object; the value is calculated on the key, not the source string.

Overrides:

hashCode in class Object

Returns:

the hash value

getSourceString

public String getSourceString()

Returns the source String object that this OraCollationKey object represents.

Returns:

the source String object

toByteArray

public byte[] toByteArray()

Converts the OraCollationKey object to a sequence of bytes.

Returns:

a byte array representation of the OraCollationKey object

getNextMultiKeys

public int[] getNextMultiKeys(byte[] keyArray)

getNextMonoKeys

public int getNextMonoKeys(byte[] keyArray)
