Method Details

getTypeAsString

public String getTypeAsString()

Description copied from interface: DataType

String which represents the type. This string will be presented to the users of the system.

Specified by:

getTypeAsString in interface DataType

Returns:

getMember

public Member getMember(String name)

Returns a member on the given name. If no such member is present return null

Parameters:

name - the name of the member to be returned

Returns:

the member with the given name

getMemberList

public List<Member> getMemberList()

getValueType

public Yamcs.Value.Type getValueType()

Description copied from interface: DataType

Return the expected Value type of an engineering value conforming to this XTCE data type

Specified by:

getValueType in interface DataType

Returns:

getMember

public Member getMember(String[] path)

Returns a member in a hierarchical aggregate. It is equivalent with a chained call of getMember(String):

 getMember(path[0]).getMember(path[1])...getMember(path[n])
 

assuming that all the elements on the path exist.

Parameters:

path - - the path to be traversed. Its length has to be at least 1 - otherwise an IllegalArgumentException will be thrown.

Returns:

the member obtained by traversing the path or null if not such member exist.

getMemberNames

public AggregateMemberNames getMemberNames()

Returns:

the (unique) object encoding the member names

numMembers

public int numMembers()

getMember

public Member getMember(int idx)

convertType

public Map<String,Object> convertType(Object value)

Parse the initial value as a JSON string.

This allows to specify only partially the values, the rest are copied from the member initial value or the type definition (an exception is thrown if there is any member for which the value cannot be determined).

Specified by:

convertType in interface DataType

Parameters:

value - value to be converted, use boxed primitive values.

Returns:

a map containing the values for all members.

Throws:

IllegalArgumentException - if the string cannot be parsed or if values cannot be determined for all members

parseStringForRawValue

public Map<String,Object> parseStringForRawValue(String stringValue)

Description copied from interface: DataType

parses the string into a java object according to the parameter encoding

Specified by:

parseStringForRawValue in interface DataType

Returns:

a java object representation

getInitialValue

public Map<String,Object> getInitialValue()

Description copied from interface: DataType

Get the initial value if any

Specified by:

getInitialValue in interface DataType

Returns:

toString

public String toString(Object v)

Description copied from interface: DataType

Converts a value to a string.

Specified by:

toString in interface DataType

Returns:
