Method Detail

containsMany

boolean containsMany()

Return true if there is a property on the path that is a many property.

pathGet

Object pathGet(Object bean)

Return the value from a given entity bean.

pathSet

void pathSet(Object bean,
             Object value)

Set a value to the bean for this expression path.

Parameters:

bean - the bean to set the value on

value - the value to set

convert

Object convert(Object value)

Convert the value to the expected type.

Typically useful for converting strings to the appropriate number type etc.

stringParser

StringParser stringParser()

Return the default StringParser for the scalar property.

getStringParser

@Deprecated
default StringParser getStringParser()

Deprecated.

Deprecated migrate to stringParser().

parseDateTime

Object parseDateTime(long systemTimeMillis)

For DateTime capable scalar types convert the long systemTimeMillis into an appropriate java time (Date,Timestamp,Time,Calendar, JODA type etc).

isDateTimeCapable

boolean isDateTimeCapable()

Return true if the last type is "DateTime capable" - can support parseDateTime(long).

jdbcType

int jdbcType()

Return the underlying JDBC type or 0 if this is not a scalar type.

getJdbcType

@Deprecated
default int getJdbcType()

Deprecated.

Deprecated migrate to jdbcType().

isAssocId

boolean isAssocId()

Return true if this is an ManyToOne or OneToOne associated bean property.

assocIdExpression

String assocIdExpression(String propName,
                         String bindOperator)

Return the Id expression string.

Typically used to produce id = ? expression strings.

getAssocIdExpression

@Deprecated
default String getAssocIdExpression(String propName,
                                    String bindOperator)

Deprecated.

Deprecated migrate to assocIdExpression().

assocIdValues

Object[] assocIdValues(EntityBean bean)

Return the Id values for the given bean value.

getAssocIdValues

@Deprecated
default Object[] getAssocIdValues(EntityBean bean)

Deprecated.

Deprecated migrate to assocIdValues().

property

Property property()

Return the underlying bean property.

getProperty

@Deprecated
default Property getProperty()

Deprecated.

Deprecated migrate to property().

elName

String elName()

The ElPrefix plus name.

getElName

@Deprecated
default String getElName()

Deprecated.
