Field Details

EMPTY

public static final ValueRow EMPTY

Empty row.

Method Details

get

public static ValueRow get(Value[] list)

Get or create a row value for the given value array. Do not clone the data.

Parameters:

list - the value array

Returns:

the value

get

public static ValueRow get(ExtTypeInfoRow extTypeInfo,
 Value[] list)

Get or create a typed row value for the given value array. Do not clone the data.

Parameters:

extTypeInfo - the extended data type information

list - the value array

Returns:

the value

get

public static ValueRow get(TypeInfo typeInfo,
 Value[] list)

Get or create a typed row value for the given value array. Do not clone the data.

Parameters:

typeInfo - the data type information

list - the value array

Returns:

the value

getType

public TypeInfo getType()

Description copied from interface: Typed

Returns the data type.

Specified by:

getType in interface Typed

Specified by:

getType in class Value

Returns:

the data type

getValueType

public int getValueType()

Description copied from class: Value

Get the value type.

Specified by:

getValueType in class Value

Returns:

the value type

getString

public String getString()

Description copied from class: Value

Get the value as a string.

Specified by:

getString in class Value

Returns:

the string

getResult

public SimpleResult getResult()

compareTypeSafe

public int compareTypeSafe(Value o,
 CompareMode mode,
 CastDataProvider provider)

Description copied from class: Value

Compare this value against another value given that the values are of the same data type.

Specified by:

compareTypeSafe in class Value

Parameters:

o - the other value

mode - the compare mode

provider - the cast information provider

Returns:

0 if both values are equal, -1 if the other value is smaller, and 1 otherwise

getSQL

public StringBuilder getSQL(StringBuilder builder,
 int sqlFlags)

Description copied from interface: HasSQL

Appends the SQL statement of this object to the specified builder.

Parameters:

builder - string builder

sqlFlags - formatting flags

Returns:

the specified string builder

cloneWithOrder

public ValueRow cloneWithOrder(int[] newOrder)

Creates a copy of this row but the new instance will contain the ValueCollectionBase.values according to newOrder.
E.g.: ROW('a', 'b').cloneWithOrder([1, 0]) returns ROW('b', 'a')

Parameters:

newOrder - array of indexes to create the new values array

equals

public boolean equals(Object other)

Description copied from class: Value

Check if the two values have the same hash code. No data conversion is made; this method returns false if the other object is not of the same class. For some values, compareTo may return 0 even if equals return false. Example: ValueDecimal 0.0 and 0.00.

Specified by:

equals in class Value

Parameters:

other - the other value

Returns:

true if they are equal
