Detailed Description

Registry which assigns unique integer indices to strings.

When registering a new name an index >= 1024 is assigned. Indices from 1 to 1023 are reserved for fast access and will never change:
1 - isotopic_range
2 - cluster_id
3 - label
4 - icon
5 - color
6 - RT
7 - MZ
8 - predicted_RT
9 - predicted_RT_p_value
10 - spectrum_reference
11 - ID
12 - low_quality
13 - charge

registerName()

UInt registerName	(	const String &	name,
		const String &	description = "",
		const String &	unit = ""
	)

Registers a string, stores its description and unit, and returns the corresponding index. If the string is already registered, it returns the index of the string.

setDescription() [1/2]

void setDescription	(	const String &	name,
		const String &	description
	)

Sets the description (String), corresponding to a name.

Exceptions

Exception::InvalidValue

is thrown for unregistered names

setDescription() [2/2]

void setDescription	(	UInt	index,
		const String &	description
	)

Sets the description (String), corresponding to an index.

Exceptions

Exception::InvalidValue

is thrown for unregistered indices

setUnit() [1/2]

void setUnit	(	const String &	name,
		const String &	unit
	)

Sets the unit (String), corresponding to a name.

Exceptions

Exception::InvalidValue

is thrown for unregistered names

setUnit() [2/2]

void setUnit	(	UInt	index,
		const String &	unit
	)

Sets the unit (String), corresponding to an index.

Exceptions

Exception::InvalidValue
