Specified by:

getRecord in interface IString

compare

public int compare(IString string,
                   boolean caseSensitive)

Description copied from interface: IString

Compare this IString record and the specified IString record

Specified by:

compare in interface IString

caseSensitive - whether to compare in a case-sensitive way

Returns:

• -1 if this < string
• 0 if this == string
• 1 if this > string

compare

public int compare(java.lang.String string,
                   boolean caseSensitive)

Description copied from interface: IString

Compare this IString record and the specified String object

Specified by:

compare in interface IString

caseSensitive - whether to compare in a case-sensitive way

Returns:

• -1 if this < string
• 0 if this == string
• 1 if this > string

compare

public int compare(char[] chars,
                   boolean caseSensitive)

Description copied from interface: IString

Compare this IString record and the specified character array

Specified by:

compare in interface IString

caseSensitive - whether to compare in a case-sensitive way

Returns:

• -1 if this < chars
• 0 if this == chars
• 1 if this > chars

compareCompatibleWithIgnoreCase

public int compareCompatibleWithIgnoreCase(IString string)

Description copied from interface: IString

Compare this IString record and the specified IString record in a case sensitive manner such that it is compatible with case insensitive comparison.

Specified by:

compareCompatibleWithIgnoreCase in interface IString

Returns:

• -1 if this < string
• 0 if this == string
• 1 if this > string

compareCompatibleWithIgnoreCase

public int compareCompatibleWithIgnoreCase(char[] chars)

Description copied from interface: IString

Compare this IString record and the specified char array in a case sensitive manner such that it is compatible with case insensitive comparison.

Specified by:

compareCompatibleWithIgnoreCase in interface IString

Returns:

• -1 if this < string
• 0 if this == string
• 1 if this > string

comparePrefix

public int comparePrefix(char[] name,
                         boolean caseSensitive)

Description copied from interface: IString

Compare this IString record and the specified character array

Specified by:

comparePrefix in interface IString

Parameters:

name - the name to compare to

caseSensitive - whether to compare in a case-sensitive way

Returns:

• 0 if this has a prefix chars
• 1 if this > chars and does not have the prefix

getChars

public char[] getChars()

Description copied from interface: IString

Get an equivalent character array to this IString record

N.B. This method can be expensive: compare and equals can be used for efficient comparisons

Specified by:

getChars in interface IString

Returns:

an equivalent character array to this IString record

getString

public java.lang.String getString()

Description copied from interface: IString

Get an equivalent String object to this IString record

N.B. This method can be expensive: compare and equals can be used for efficient comparisons

Specified by:

getString in interface IString

Returns:

an equivalent String object to this IString record

delete

public void delete()

Description copied from interface: IString

Free the associated record in the Nd

Specified by:

delete in interface IString

length

public int length()

Specified by:

length in interface IString

Returns:

the length of the string
