Property Detail

isAssoc

Return true if any path of this path contains a Associated One or Many.

Method Detail

getAssocOneIdValues

Object[] getAssocOneIdValues(Object bean)

Return the Id values for the given bean value.

getAssocOneIdExpr

String getAssocOneIdExpr(String prefix,
                       String operator)

Return the Id expression string.

Typically used to produce id = ? expression strings.

getAssocIdInValueExpr

String getAssocIdInValueExpr(int size)

Return the logical id value expression taking into account embedded id's.

getAssocIdInExpr

String getAssocIdInExpr(String prefix)

Return the logical id in expression taking into account embedded id's.

isAssocId

boolean isAssocId()

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

isAssocProperty

boolean isAssocProperty()

Return true if any path of this path contains a Associated One or Many.

isLocalEncrypted

boolean isLocalEncrypted()

Return true if the property is encrypted via Java.

isDbEncrypted

boolean isDbEncrypted()

Return true if the property is encrypted in the DB.

getDeployOrder

int getDeployOrder()

Return the deploy order for the property.

getStringParser

StringParser getStringParser()

Return the default StringParser for the scalar property.

getStringFormatter

StringFormatter getStringFormatter()

Return the default StringFormatter for the scalar property.

isDateTimeCapable

boolean isDateTimeCapable()

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

getJdbcType

int getJdbcType()

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

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).

elGetValue

Object elGetValue(Object bean)

Return the value from a given entity bean.

elGetReference

Object elGetReference(Object bean)

Return the value ensuring objects prior to the top scalar property are automatically populated.

elSetValue

void elSetValue(Object bean,
              Object value,
              boolean populate,
              boolean reference)

Set a value given a root level bean.

If populate then

elSetReference

void elSetReference(Object bean)

Make the owning bean of this property a reference (as in not new/dirty).

elConvertType

Object elConvertType(Object value)

Convert the value to the expected type.

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