Detailed Description

Internalizes a translation table.

This class internalizes an Isis translation table and provides group/key searches and value translations. The group names listed are the output names used by applications to get the input names and values. There is only one level of groups and groups are not allowed to be nested. The Group names can NOT be repeated. OutputGroup is a comma delimited list of objects and/or groups in the input label. Traversing this list within the input label will lead to the correct level to find the input keyword. OutputKey is the keyword within the group which holds the information. OutputDefault is the value used if there is no value for the keyword. Translation is the output and corresponding input values. Translation may be repeated as needed. An example piece of a tranlation file:

Group = DataStart
OutputKey = ^IMAGE
OutputDefault = 1
Translation = (*,*)
EndGroup
Group = DataFileRecordBytes
OutputKey = RECORD_BYTES
Translation = (*,*)
EndGroup
Group = CoreSamples
OutputGroup = IMAGE
OutputKey = LINE_SAMPLES
Translation = (*,*)
EndGroup
Group = CorePixelType
OutputGroup = IMAGE
OutputKey = SAMPLE_TYPE
OutputDefault = LSB_INTEGER
Translation = (Integer,LSB_INTEGER)
Translation = (Integer,MSB_INTEGER)
Translation = (Integer,PC_INTEGER)
Translation = (Integer,MAC_INTEGER)
Translation = (Integer,SUN_INTEGER)
Translation = (Integer,VAX_INTEGER)
Translation = (Natural,UNSIGNED_INTEGER)
Translation = (Natural,LSB_UNSIGNED_INTEGER)
Translation = (Natural,MSB_UNSIGNED_INTEGER)
EndGroup
Group = CoreOrganization
OutputGroup = IMAGE
OutputKey = BAND_STORAGE_TYPE
OutputDefault = BAND_SEQUENTIAL
Translation = (BSQ,BAND_SEQUENTIAL)
Translation = (BIL,LINE_INTERLEAVED)
Translation = (BIP,SAMPLE_INTERLEAVED)
EndGroup
