Method Detail

values

public static DefaultSQLValueDeserializer[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DefaultSQLValueDeserializer c : DefaultSQLValueDeserializer.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DefaultSQLValueDeserializer valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

addValueProcessor

public void addValueProcessor(SQLValueDeserializer.ValueProcessor valueProcessor)

Description copied from interface: SQLValueDeserializer

Add a deserialized value processor.

Specified by:

addValueProcessor in interface SQLValueDeserializer

Parameters:

valueProcessor - the value processor to add (not null)

public <T> T deserialize(SQLExecutionContext context,
                         com.holonplatform.core.TypedExpression<T> expression,
                         Object valueToDeserialize)
                  throws SQLException

Description copied from interface: SQLValueDeserializer

Deserialize the value associated to given expression, to obtain a value type which matches the expression type.

Specified by:

deserialize in interface SQLValueDeserializer

Type Parameters:

T - Expression type

Parameters:

context - Execution context

expression - Expression for which the deserialization is invoked

valueToDeserialize - Value to deserialize

Returns:

Deserialized value

Throws:

SQLException - If value cannot be deserialized using given expression type
