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 java.lang.String getString()

Description copied from class: Value

Get the value as a string.

Specified by:

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

compareTypeSafe

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

Specified by:

compareTypeSafe in class Value

Parameters:

o - the other value

mode - the compare mode

provider - the cast information provider
