Remove java wrapper from descriptor — rm

Clean up left-behind wrappers used to communicate with Java code using 'rJava'.

Usage

rm_jwrapper(x)

Arguments

x: raw_spct or raw_mspct object with attribute instr.desc set.

Value

a copy of x possibly with an updated instr.desc attribute embedded.

Details

Field w contains a wrapper on a Java object used to communicate with the OmniDriver driver during data acquisition. Once the current connection between R and a spectrometer ends, these wrappers are invalidated, becoming useless. However, if present they create a dependency on 'rJava', possibly triggering errors. In recent versions of 'ooacquire' this wrapper is removed immediately after acquisition. However, the instrument descriptor of spectral objects created with versions of 'ooacquire' for some years ago can contain a member storing a useless Java wrapper. This function removes this field if present.

Note

Method getInstrDesc() removes member field w from the returned value but does not modify its argument.
