provider - the cast information provider

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

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

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

equals

public boolean equals(java.lang.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
